United States Patent This invention relates to radiating or incandescent burners of thelkind embodying a distribution chamber for combustible gas received from a mixing tube or space, an out- 0 let from this distribution chamber being covered by a refractory diaphragm comprising a layer of gas-'pervious gauze or two or more such layers in mutual intimate. con- Examples of such burners are described inBritish patent It is anobject of this. invention to 'providea radiating or incandescentbu-rner of the kind referredto having means for producing a substantially uniform heating effect' over .areceiving area spaced apart. from phragm and lying parallel thereto. 0
- It is a further object of this invention to prevent any partial burning of combustible gas .in, and hence to prevent the emission of products of. incomplete combustion specification No.
the dia- '7 5 and objectionable smells from, a radiating-or, incandescent burner of the kind referred to,- -,the'burner having means for producing a substantiallyuniform heatingeffeet over, a receivingarea spaced-apart from the diaphragm and lying parallel thereto.
Further-objects will become apparent tion proceeds. t g The present invention consists in a radiating or incandescent burner of the kind referred to wherein ascreen is. providedin proximity to a central portion of the refractory diaphragm to prevent or restrictthe passage of gas through the said central portion so as to produce a substantially uniform heating effect over a receiving area spaced apart from the diaphragm. I
The area of thescreen is,preferably approximately one as the descriptenth of the total areaof the outlet, for instance, from one eighth to one twelfth of this total area. v
If desired, the screen can be providedin proximity only to the central portion of the refractory diaphragm; such an arrangement compares favourably with an arrangement where a screenhaving suitably disposed holes of the correct dimension is disposed to coincidewith the whole area of the refractory diaphragm.
It is more convenient to arrange the screen on the inside of the diaphragm, but in some instances it has been found that the screen can move slightly away from the diaphragm, sufficient to allow combustible mixture to creep between the screen and the diaphragm. If this creeping occurs, the combustible mixture may be only partly burnt between the screen and the diaphragm, with the result that products of incomplete combustion escape and objectionable smells are produced, particularly if the organic sulphur content of the combustible gas is high, when a mixture of sulphur oxides and aldehydes of a somewhat pungent nature may be emitted. In order to prevent this creeping, it is highly desirable that an inner screen be provided on the inside of the diaphragm and an outer screen be provided on the outside of the diaphragm, opposite the inner screen.
The two screens may be fixed in position by attaching one to the other through the diaphragm, e.g. by riveting, bolting or screwing. In some cases they may be attached by welding. It is highly desirable that the outer screen be not smaller than the area of the inner screen in contact with the diaphragm (or if this inner screen contacts the diaphragm by way of a continuous flange or FIGURE 1 j Patented Jan. 17, 1967 free .er around its edge portions; in order to tension the diaphragm, an. adjustable tensioning means can be provided to bias the said inner screen outwardly against the diaphragm. This tensioning meanscan be providedin a simple manner by a screwed member passing through a casing of the distribution chamber and abutting said screen; the screwed member can be locked in position-for instance by a lock-nut and a gland can be arranged to give a gas-tight. seal between the screwed member and the casing. Other arrangementsv may be used to tension the diaphragm, for instance using set? screws to draw out the periphery-of the diaphragm, but using the tensioning means above, the periphery of the diaphragm may be fixed rigid ly'to the burner casing, preferably, by being merely clamped-in position between .a clamping frame andthe edge portions of the casing. vThe invention will be further described by way of example, with :reference to the. accompanying drawings, of
which:
FIGURE 1 is a top view of one embodiment of a burner in accordance with the invention;
FIGURE 2 is-a cross-section along the.line,IIII of FIGURE 3 is an exploded view of a second embodiment of-the invention; and a v ,FIGURE 4 is across section on an enlarged scale of a detail of the embodiment shown in FIGURE 3.
I The burner shown-in FIGURES 1 and 2 has a hood- 1 through one side (usually a longer side) of which passes a burner mixing tube 2; the mixing tube 2 is sealed to the .hood 1 at its point of entry and is secured in position bya self-tapping screw .3 which is located in a depression 4 inlet tube baflle 5 to the inner end of the tube 2, this bafile 5 being of such a shapeand curvature as to provide a substantially even distribution of the combustible mixture inside the hood 1. I
The hood 1 is provided with flanges 6 around its lower edge portions, and these flanges 6 carry a double wire gauze diaphragm 7, the diaphragm 7.being of slightly larger size than the size across the flanges 6 and having its corners. mitred, so that the edges of the diaphragm .7 can be turned back through over the flanges 6, and held in posit-ion by a skirting clamping frame 8; the corners of the frame 8 are also mitred, and its edges are wrapped around the edges of the diaphragm 7 and clamped in position to closely embrace the peripheral portions of the diaphragm 7.. It will be appreciated that by using suitable tool pressure, a tight lap joint can be formed suflicientlywell to be gas-tight without the aid of gaskets.
To a centralv portion of the diaphragm 7 are attached an inner plate 9 and an outer plate 10; these plates are held firmly together, preferably by means of rivets 11, but other attaching meansmay be used. Though the outer plate 10 is substantially planar, the inner plate 9 has a continuous protuberance 12 extending around its peripheral edge portions, and this protuberance 12 makes contact with the diaphragm 7. The area definedby this protuberance 12 is approximately one ninth of the area of the opening" in the frame 8. In a central portion, the inner plate 9 is provided with an indentation 13 in the concave inner side of which rests the end of a tensioning screw 14. The upper end of the tensioning screw 14 is screwed into a gas-tight bush 15 which is secured to the depressed portion 4 of the hood 1. The tensioning screw 14 can be screwed down to tension the diaphragm 7, and a slot 16 is provided in the top of the tensioning screw 14 to receive a screw-driver; in addition, a lock-nut 17 is provided to lock the screw 14 in adjusted position.
In a second embodiment of the invention shown in FIGURES 3 and 4, like parts have been given the reference numerals accorded to those parts in FIGURES 1 and 2. The area defined by the protuberance 12 is approximately one eleventh of the area of the opening in the frame 8. A vertical deflector 19, having side portions bent perpendicularly thereto with inclined edges, is secured to the side of hood 1 below the depression 4. This deflector 19 forms part of a combustible gas mixture spreader or diffuser which serves to provide a substantially even distribution of the combustible gas mixture inside the hood 1. The other part of the gas mixture spreader is an inclined deflector plate 20 extending from one side of the inner plate 9. Furthermore, four arms 21 of channel shaped cross section extend diagonally outwardly and upwardly from each corner of the plate 9 so that when the tensioning screw is screwed down to tension the diaphragm 7, in addition to the contact made by the protuberance 12 with the diaphragm 7, the rounded ends of the arms 21 also make contact with the diaphragm 7 at places approximately midway between the indentation 13 and the outer corners of the diaphragm 7, thus serving to assist in tensioning the diaphragm 7 without seriously impeding access of the gas mixture thereto;
Furthermore, a sealing ring 22 externally welded appropriately to the periphery of burner mixing tube 2 is secured by self tapping screws to the side of the hood 1 and the self tapping screw 3 now serves only to locate the mixing tube in its correct position.
Though the burner is shown as being of generally rectangular shape, it will be appreciated that other shapes would be possible, and also although the inner and outer plates 9 and are shown as being arranged to allow no combustible mixture to pass through them, they could be provided with apertures, which if desired could be punched out in a manner to provide means for spacing the plates 9 and 10 from the diaphragm 7, thus providing some degree of heating in this central portion of the diaphragm 7.
The burner can be appropriately supported above a grilling platform at any convenient height with a gas injector arranger to supply a jet of gas to the inlet of the mixing tube 2. At this inlet it is found advantageous -to provide a flash protector 18. This flash protector 18.
consists of a flange attachment adjacent the inlet of mixing tube 2 in the form of a solid disk-like plate disposed at right angles to the mixing tube axis and having its lower part depending a substantial way below the mixing tube 2. When the gas is first turned on a combustible mixture is formed outside of and below the diaphragm 7 and this mixture rapidly fills the space inside the depending wall 8 of clamping frame 8. This mixture can easily fill around the periphery of walls 8' and, being less dense than the surrounding air, rise around flange assembly 8' and be deflected toward gas injector 23. The flash caused by lighting the burner while causing the combustion zone to rapidly settle toward the outside of diaphragm 7 can 4 hood 1, the mixing tube 2 and the bafile 5 could be diccastings or sand castings, for example, of iron, copper or copper alloy, or aluminium or aluminium alloy. The inner and outer plates 9 and 10 are preferably made of heat and corrosion-resisting metal, as are the rivets 11.
While two embodiments have been particularly described herein, it is understood that the invention is not restricted to these embodiments, but is only limited by. the following claims,
I claim:
